How to merge overlapping rectangles ?

I have used BWLABEL and BOUNDINGBOX command to get the following image.

Here we can see in the right corner two rectangles are overlapping and as we can see the bigger rectangle completely encloses the smaller one. How can I remove the smaller one and keep the big rectangle alone? Also I don't want any rectangles over lapping.

Any help would be appreciated.

Hi Rajeshwar,

There is no as such function which can remove inscribed rectancles.

But you may write a similar code like this in which i want to return that rectangle which has larger area.

A = [1 2 5 6]; %Rectangle A
B = [1 2 3 4]; %Rectangle B

%Rectangle B is completely inscribed in Rectangle A

area = rectint(A, B); %returning area inscribed
if ~area %if area is not zero
    return max(A, B); %return maximum area rectangle
end

rectangle('Position', max(A,B)); %plotting maximum area rectangle
axis([0 10 0 10]);

You may look at these documentations for further help:

Rectangle intersection area - MATLAB rectint (mathworks.com)

Create rectangle with sharp or curved corners - MATLAB rectangle (mathworks.com)

Hope this Helps!
